phone=document.ship_info.phone.value;

alert("You entered an invalid phone number.");
}
The replace doesnt do anything. Cant get even the most simple example to work like:
text="java";
text.replace(/java/, "not java");

I make this mystake, myself quite often.
The correct form, would be:
text="java";
text = text.replace(/java/, "not java");The important thing being that strings are 'immutable'.
If you want to change a string, you need a new one, which is what string methods produce. They don't change the original.
